Daily Status Report as of 136/1200Z.
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed WF/PC-2 5233 (Stellar Populations and Clusters in
Elliptical Galaxies (WC08))
The WF/PC-2 was used to make deep observations of elliptical galaxy
NGC-3379-PO which is located in the Coma Cluster of galaxies to
study its stellar population. The observations were complete as
scheduled, and no anomalies were noted.
1.2 Completed WF/PC-2 5560 (WF/PC-2 Cycle 2 Calibration: Internal
Monitor. 1)
The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the
optical alignment, and for contamination. The observations were
executed as scheduled, and no anomalies have been noted.
1.3 Completed FOS/RD 5652 (SINS: The Supernova Intensive Study Target of
Opportunity: Cycle 4 )
The Faint Object Spectrograph (Red Side) was used to make
observations of supernova SN1994I and its circumstellar matter. The
onboard target acquisition was successful, and the observations were
executed without problems. Seven observations were received and
displayed. No anomalies were noted.
1.4 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats,
Large Set)
The WF/PC-2 was used to make a set of Earth flat calibration images
using different filters in order to construct high quality flat
fields of the OTA illumination pattern. A total of eight images were
received and displayed. Two images were underexposed, one was
saturated, and five were reported to be okay.
1.5 Completed Three Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR
Radio Galaxies)
The WF/PC-2 was used to make snapshot images of radio galaxies
3C208.1. 3C293.1, and 3C469.1. The first two sets of observations
were received and displayed. They were reported to be okay. The
third set of observations still remains on the Science Tape
Recorder, and will be analyzed later.
1.6 Completed Eight Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and
Spiral Galaxies)
The WF/PC-2 was used to make observations of galaxies NGC-4592,
NGC-4546, and 3C293.1 The observations were executed as scheduled.
The first set of observations showed no target, and the other images
were reported to be okay. No other anomalies were noted.
1.7 Completed WF/PC-2 5454 (Ellipticals With Kinematically Distinct
Cores: Cycle 4 Medium)
The WF/PC-2 was used to make observations of the small elliptical
galaxy NGC-1700 which contains a massive core which is kinematically
distinct from the rest of the galaxy. The observations were executed
as scheduled, and no anomalies were noted.
1.8 Completed Two Sets of GHRS/1 5417 (A Search for the Physical
Processes on Jupiter)
The High Resolution Spectrograph (Side One) was used as part of a
program to observe atomic hydrogen emission at different latitudes
and longitudes on the planet Jupiter. The first Wave-Cal was
reported to be okay, and the second was reported to have a very weak
signal. Three Science observations were received and displayed. They
were reported to be okay.
1.9 Completed FGS 5337 (Linking the HIPPARCOS to the Extragalactic
Reference Frame: NEWHIP-C)
The FGSs were used to make astrometric observations of NEWEGOC-50
and 620-REF to help tie the HIPPARCOS and extra-galactic reference
frames together. The last seven of 11 target positions were
monitored in real-time. The target was not located at position nine
or position 11. The OSS reported that they suspect that the
many-second multiple-event recenterings in the first few minutes of
position 11's measurement may have caused the anomaly.
1.10 Completed FOC/96 5636 (FOC Onboard Bright Object Protection Test)
The Faint Object Camera was used to make dark exposures to help
evaluate the new bright object protection software for the FOC. Two
dark images were received and displayed. They were reported to be
okay.
1.11 Completed Three Sets of WF/PC-2 5370 (HST Medium-Deep Survey: Cycle
4 Medium, High Galactic Latitude: CR-SPLIT)
The WF/PC-2 was used in parallel with the prime science
observations
to make high galactic latitude observations as part of a
medium-deep sky survey. The first two sets of observations
contained two images each. They were reported to be okay. The third
set of observations still remains of Science Tape Recorder #1, and
will be analyzed later.
1.12 Completed FGS 5174 (Astrometric Companion Search: Cycle 4)
FGS #3 was used to make astrometric observations of the possible
binary dwarf star W-922 to look for an astrometric unseen, low-mass
companion. The continuous scans executed on Fine Lock with no
apparent problems.
1.13 Completed WF/PC-2 5091 (GTO High Latitude Parallel Program: Cycle
4)
The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations greater than +/-30
degrees. Two images were received and displayed. They both were
reported to look okay.
1.14 Completed FGS 5333 (Linking the HIPPARCOS to the Extragalactic
Reference Frame: BR12-23: Part 2)
The FGSs were used to obtain astrometric observations of star
1514-241IN whose apparent position lies near extragalactic objects.
The astrometry observations were monitored whenever the telemetry
was available. The Stop Flag was seen at least twice. It appears
that some observations succeeded and some failed.
1.15 Completed WF/PC-2 5386 (Stellar Populations of Leo II Dwarf
Spherical Galaxy)
The WF/PC-2 was used to make observations of the small dwarf galaxy
known as Leo II in order to construct an H-R diagram of the
component stars. The observations were executed as scheduled, and no
anomalies were noted.
1.16 Completed WF/PC-2 5375 (High Resolution Images of Virgo Galaxies
with Kinematically Distinct Cores)
The WF/PC-2 was used to make observations of galaxy NGC-3368, which
is located in the Virgo Cluster. Four images were received and
displayed in the OSS. They were reported to look okay.
1.17 Completed WF/PC-2 5415 (The distance to the M-96 Galaxy Group:
Cycle 4 Medium)
The WF/PC-2 was used to make observations of Cepheid variable stars
within the galaxy UGC-5889 which itself is located in the M-96
galaxy cluster. Two observations were received and displayed. There
were no reported problems.
1.18 Completed WF/PC-2 5149 (High Resolution Imaging of Circumstellar
Shells Around Evolved Stars)
The WF/PC-2 was used to make observations of the hot blue variable
star HD94910 (aka, AG Car). Three images were received and
displayed. They were reported to be excellent. More data still
remains on the Science Tape Recorder, and will be analyzed later.
1.19 Completed WF/PC-2 5475 (A Snapshot survey for Blue Stragglers in
Magellanic Cluster Cores)
The WF/PC-2 was used to make short exposure snapshot images of the
blue straggler stars located in populous cluster NGC-1850. All of
the observations were executed as scheduled. The data remains on the
Science Tape Recorder, and will be analyzed later.
1.20 Completed FGS 4884 (High Speed Astrometry: A Search for Planetary
Companions to Low Mass Stars)
The FGSs were used to make observations of Barnard's star to look
for astrometric companions (i.e., a Jupiter-sized companion). The
OSS was able to monitor most of the observations in real-time, and
no problems were seen.
1.21 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4)
The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. This is part of a survey to take
pictures of a large number of fields within 30 degrees of the
galactic plane. The observations were executed as scheduled, and no
anomalies were noted.
1.22 Completed FGS 5336 (Linking the HIPPARCOS to the Extragalactic
Reference Frame.)
The FGS #3 was used to make astrometric observations of NEWEGOB-36.
The astrometric observations occurred entirely within LOS, and could
not be monitored. The data will be analyzed after the Science Tape
Recorder #1 playback.
